The invention relates to a metal-filled resin composition, in particular for use in a 3D printing method, based on layer-by-layer photopolymerization for producing components, in which the resin composition comprises a photopolymerizable matrix component and a dense metal filler having a certain minimum volume percentage and a photoinitiator. A component is additively manufactured using optical radiation by selectively curing a metal-filled resin composition layer by layer. In particular, the invention relates to radiation-absorbing components produced with high precision on the basis of a lithographic additive method, such as SLA, in which a wall thickness up to less than 100 [mu] m can be achieved by means of the specially selected composition used, while still having a large radiation hardness and a high surface quality. 本发明涉及一种填充金属的树脂组合物，尤其用于3D打印方法，该方法基于逐层的光聚合用于制造构件，其中，树脂组合物包含可光聚合的基体成分和具有某个最小体积百分比的致密金属填料以及光引发剂。通过逐层地、选择性地固化填充金属的树脂组合物利用光辐射增材制造构件。本发明尤其涉及基于平版增材方法、如SLA高精度地制造的辐射吸收构件，其中，由于特殊地选择使用的组合物可实现在仍然较大的辐射硬
